The ultimate mental fitness program" (David Heinemeier Hansson, coauthor of Rework), The Stoic Challenge teaches us how to respond to the challenges of our increasingly unpredictable age. In this practical, refreshingly optimistic guide, philosopher William B. Irvine explains how centuries-old wisdom can help us better cope with everything from the everyday stresses of modern living to its significant crises. The Stoic Challenge uniquely combines insights from ancient Stoics like Marcus Aurelius, Seneca, and Epictetus with techniques discovered by contemporary psychological research, such as anchoring and framing. The result is Irvine's surprisingly simple, updated "Stoic test strategy," which teaches us how to dramatically alter our emotional response to life's stumbling blocks. Not only can we overcome these obstacles-we can benefit from them, too.
